The selling price of 5 articles is the same as the cost price of 3 articles. The gain or loss per cent is :
-
- 20% gain
- 25% gain
- 33.33% loss
- 40% loss
Correct Option: D
According to question , we have
C.P. of 3 articles = S.P. of 5 articles
| ⇒ | = | S.P. | 3 |
Loss = S.P. - C.P. = 5 - 3 = $ 2
| Loss% = | × 100 | 5 |
Loss% = 2 × 20 = 40%
Second method to solve this question :
Here, p = 3, q = 5
| Loss % = |  | p - q |  | × 100 | |
| q |
| Loss% = | | 3 - 5 | | × 100 = – 40% (–ve sign shows loss) | |
| 5 |
Loss% = 40%
